The Geology of Mount SiebaNj in the JJ^yper Pitnjdb, hy W. WaageNj 

 Ph.D., and A. B. Wynne, R G. S., Geological Survey of India. 

 Mount Sirban (Seer Bun), rising close to the southward of Abbota- 



bad station, is one of the most lofty of the Hazara* hills : a portion 



of those which form the outworks of the north-western Himalaya 



bordering the Upper Punjab. 



The latest, if not the only, published reference to the geology of 

 this locality of which we are aware occurs in Dr. Albert Verchere's 

 'paper read before the Asiatic Society in Calcutta on " Kashmir, the 

 Western Himalaya, and the Afghan Mountains,"t communicated in 

 1866-67. In this paper Dr. Verchere gives a rough section with a 

 description of the northern [ i. e., north-eastern ] end of the mountain, 

 stating that he recognised carboniferous limestone resting upon volcanic 

 rocks. The beds above these he referred in a general way to the Jurassic 

 formation, and the highest strata on the northern side of the mountain 

 to the nummulitie limestone : the detailed descriptions of the rocks 

 and construction of the section which he gives are, however, so inade- 

 quate to represent the facts as to render their recapitulation undesirable. 



At first sight the mountain looks very similar to others in the 

 vicinity, formed chiefly of limestone and shale, but presents a strong con-
